—EBUS-TBNA Average Number of Needle Passes per Lymph Node by Use of ROSE and Needle Gauge
| Procedure | 21 Gauge (n = 497 lymph nodes) | 22 Gauge (n = 2,271 lymph nodes) | P Valuea |
| Total (N = 2,768) | 3.5 ± 1.2 | 4.2 ± 1.3 | < .01 |
| ROSE yes (n = 2,064) | 3.7 ± 1.1 | 4.6 ± 1.2 | < .01 |
| ROSE no (n = 704) | 3.2 ± 1.3 | 3.2 ± 1.1 | .69 |
Data are presented as mean ± SD. EBUS-TBNA = endobronchial ultrasound-guided transbronchial needle aspiration; ROSE = rapid onsite cytologic evaluation.
